FM Transmitters?!?!

Still waiting to talk to my friend. He's on vacation on some tropical island in the caribbean.
Here's my concern. I can't find anywhere that describes how the Alpine KWE155B works other than with the EX-10. But I know for a fact he did not have an EX-10. What confuses me is I dont know how the KWE155B creates a signal that can be picked up by the radio, I believe its just an antenna splitter. I know the Ipod/Iphone can't do it, so I'm wondering if he had some other kind of modulator in the car or something.
I did however find deals on everything through amazon though if you think you might like it. The ex-10 does look pretty sweet. It would also allow you to charge and fully control your ipod from the touch screen rather than having to handle your ipod.
KWE155B $24.99 Amazon.com: Alpine KWE155B Antenna Switch Box for EX10: Electronics
Alpine EX-10 $28.70 Amazon.com: Alpine eX-10 - Bluetooth hands-free car kit / iPod interface adapter w/built-in FM modulator: Electronics
40gm10 adapter $4.68 Amazon.com: Metra 40-GM10 GM Antenna Adapter: ANTOnline
40gm20 adapter $4.68 Amazon.com: METRA Ltd 40-GM20 Gm Radio Antenna with Mini Adapter: ANTOnline

This would still be all plug and play.

The other option is a standard wired fm-modulator. but they would require you to tap into a power source and splice a single wire. Which isn't hard to do but if you have never done it before it can be intimidating. A local stereo shop would probably do it for you for $20 or so.
FRYS.com

Is that everything you need? Thats like 100 bucks with the EX-10. Why would I even need that? It seems like an extra thing just if you want the interface, which I don't.

And could Best Buy install something like that from the FRYS.com?

This is the one that I bought and it works great:

Amazon.com: Scosche FM-MOD02 FM Modulator for iPod, Satellite Radio or Portable Music Player:…

You plug it inline with the antenna (like the other) with the GM adapters then you run your power for the switch. It has a couple of channels to choose from that it simulates to give you your hookup. It does not take out the functionality of your radio at all even when it's on, only takes over the one station, I even have XM hooked up before this thing.

I don't think Best Buy will install anything they don't sell. Yes that is everything you need. Its less than $100 more like $75 shipped.
The reason you would need the ex-10 is because it is a modulator, it converts the signal from your ipod into a radio signal that your radio can understand.
The thing about the ex-10 is it does much more. Its a touch screen, It charges your device, it has built in bluetooth for your phone etc.. Its all up to you what you want to do.
